EDGE-GAGE FOR USE ON SLU GGING, NAILING, 0R LIKE MACHINES.

Specification of Letters Patent.

Patented May 30, 1911.

Original application filed October 22, 1907, Serial No. 398,589. Dividedand this application filed December 18, 1909. Serial No. 533,964.

To all whom it may concern:

Be it known that I, MARK THOMAS DENNE, a subject of the King of GreatBritain and Ireland, residingat Rushden, Northampton county, England,have invented new and useful Improvements in Edge-Gages for Use onslugging, Nailing, or Like Machines, of which the following is aspecification.

This invention has reference to an 1mproved edge gage suitable for useonslugging or nailing machines or the like, in which the gage is set forthe different rows of slugs to be driven by the operator merely pressingon a rod or a knob or equivalent thereon and which rows of slugs may bespaced apart towithin limitsany desired and predetermined extent and inwhich the gage is reset, after say one boot has been completed ready forthe next, by the operator merely pulling out the bar carrying the edgeroll.

My invention is illustrated in side elevation in Figure 1 of the accomanying drawing Fig. 2 being a sectiona view on line X-X of Fig. 1; andFig. 3 is a face view of one of the disks hereinafter to be referred to.

In carrying my invention into practice I mount an edge roll 46 orequivalent on a bar 47 which latter is slidably carried by a suitableframe C to be attached to the slugging or other machine. The edge roll46 or equivalent is to serve as the guide against which the work is heldwhen being operated on and the frame, it will be understood, must befixed to the machine so that the said edge roll or equivalent issupported and adapted to move in proper relation to the horn D or otherwork support in the usual manner.

The bar 47 is formed with a rack 48 with which a toothed pinion 49 gearsand I provide a spring 61 attached at one end to the bar 47 and at itsother end to a stationary part for example to the frame 0, which springserves to move the bar 47 and consequently the edge roll in thedirection of the arrow Gr, 2'. e. away from the horn, when the pinion 49is set free as will be hereinafter ex lained.

n the extension of the shaft 50 on which the pinion 49 is fixed I mounta series of disks 51 each of which is formed at one edge with a flangeor rim 55 so that when the disks are placed together as shown a seriesof peripheral grooves 59 are formed between the flanges or rims of thedisks. Each flange or rim 55 has a part out out so as to form a gap 56and the ,disk at one edge of the gap is formed with a projection or stop58 said stop being flush with said edge.

At a suitable position, for example below the disks 51, I provide aslidable rod 54 having a finger 53 to project into one or other of thegrooves 59 and which rod is normally impelled in the direction indicatedby the arrow 0 by a spring 57 the rod 54 being incapable of rotarymovement.

It will be evident that the spring 61 will have the effect to rotate thedisks 51 until the finger 53 is contracted by the stop 58 in theparticular groove 59 in which the finger is for the time situated, saidfinger preventing further rotation of the disks and conse in the firstgroove 59 (marked 1) the stop on the disk will be against the saidfinger and the gap 56 in the rim of said disk will be opposite or inalinement with said fin er. If now the rod 54 be ushed in the directionopposite to that indicated by the arrow 0, i. e. in opposition to thespring 57, the finger 53 will pass through the gap in the rim 55 of thefirst disk and will enter the grooves 59 of the second disk. The effectof this will be that the disks will be permitted to rotate until thestop 58 on the second disk contacts with the finger 53 the extent or'amount of rotation being according to the angular distance between thestop in the groove of the first and that in the groove of the seconddisk, and consequently the bar 47 and its edge roll will have moved awayfrom the horn a proportional distance so that the distance from the edgeof the work at which the second row of slugs is to be driven will havebeen determined. If the rod 54 be again depressed as described, itsfinger will pass into the third groove and the edge gage will move afarther distance from the horn, and so on.

The disks will of course be so adjusted on their shaft 50 that the edger011 will move the requisite distance when the rod 54 is operated.

In'order to move the edge roll toward the horn it is only necessary topull it in that direction-against the action of spring 61- and tofacilitate this I provide the bar 47 with a lug 62 which may be engagedby the operators finger. The pulling of the edge roll as described is torotate the pinion 4E9 shaft 50 and disks 51 and as these latter by thisrotation will in succession bring their gaps 56 opposite the finger 53of the rod 54 the spring 57 will in succession push said finger throughthe said gaps until the pull on the lug 62 ceases or until the finger 53has passed through the gaps of all the disks when it will come incontact with a plate 80 which I provide on the outside of the disks 51.

The disks may be held frictionally together and in engagement with theshaft 50 by a set-screw 81 and washer 82 or by any other known means.

What I claim as my invention and desire to secure by Letters Patent is1- An edge gage for use on slugging, nailing or like machines,comprising an edge roll carried on a bar slidable in a frame, a springtending to move the said bar in a direction away from the Work supportof the machine to which the gage is applied, a rackon' said bar gearingwith a toothed pinion fixed on a spindle rotatably carried by the saidframe, a series of disks adjustably fixed on said spindle and havingprojecting rims formed with gaps and with stops adjacent to said gaps,and a spring-operated slidable rod having a finger to project betweensaid rims, all substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
